' Application filed e 7,1906. Serial No. 320,534-

Indiana, have invented a certain new and useful Attachment for Cultivators; and I do hereby declare that the following is a full,

clear, and exact description thereof, refer-.

ones being had to the accompanying drawin s, in which like figures refer to like parts.

lhe object of this invention is to provide a convenient and effective means in or adapted to be attached to cultivators for regulating the depth of the shovels during use. Sai mechanism, as shown herein, is an attachment to a common type of cultivator, and it ma bui t or in use or it may be built at the same time as the rest of the cultivator.

The full nature of this invention will be more fully understood from the accompanying drawings and the following description and claims.

In the drawings, Figure l is a side elevation of a cultivator with said invention in connection therewith, the tongue of the cultivator be broken away and the parts in their norma osition. Fig. 2 is the same with the shovels depressed and their elevated position shown by dotted lines. Fig. 3 is a plan view of the'right-hand half of the cultivator shown in Figs. 1 and 2, lateral positions of the gang being shown by dotted lines.

The drawings herein show in detaila wheel and an axle 1 1, cranked substantially as shown, that carries a frame 12 upon it, to the rear end of which a seat 13 is secured and to the forward end of which a tongue 14 is secured. A brace 15 extends from the axle to the tongue. 16 is a swingletree connected with vertical-bars 17, fastened on the tongue. An arm 18 extends downwardly from the tongue and carries a transverse bar 19, to whic a gang-beam 20 is fulcrumed at 21.

Said beam 20 carries the shovel 22, and to? the sides of said beanrauxilia'ry beams 23 and 25 are bolted, the former-carrying a shovel 24 and the latter a shovel 45. v

The foregoing constitutes an ordinarv e of cultivator inwhich the gang of shovels The I the op ri es upon the ground b avit gang is moved laterally byt e oot o 'erator.engaging the foot-rest 26. v

My invention consists in adding to the foregoing the following mechanism: A frame be attached to a cultivator alreadyforth.

.2. In a cultivator, the combination of a.

consisting of the bars and 31 is secured rigidly to the ang. In the drawings herein said bars are c amped to the middle beam 20, so as to be rigid. To the rear vertical portion of the frame, as herein shown to the bar 31, I pivot two parallel bars 32 and 33, one above the other and of equal length, so that the ends of said bars may move vertically. To the outer end of said bars I pivot the caster-bracket 34, and in that bracket a castershaft 35 is swiveled in a vertical osition, and a swivel-wheel 36 is carried at t e lower end ofsaid caster-shaft, the lower end of said ca'ster-shaft being curved or bent, as shown.

To the bar 32 I secure a hand-lever 37, said lever in the drawings being shown integral with said bar 32 and extending within reach of the operator. It oscillates vertically in a segmental guide 38, which has notches or teeth adapted to be engaged by a bar 39 on the end of the bar-lever 40, whereby said lever 37 is locked in any tion.

desired posi- Theshovels are depressed and made to run deeper in'the soil by depressing the handle 37, as shown in'Fig. 2. They are elevated by the elevation of i said hand-lever, as shown by dotted lines in Fig. 2, and they ma be set at any intermediate position desire to secure by Letters Patent, is

1. In a cultivator, the combination of a gang-beam, a vertically-disposed frame secured. thereto, a pair. of horizontally-disposed parallel bars pivoted to the said frame and extendin rearward, a swiveled groundwheel pivotal y connected to the rear ends of saidbars, a hand-lever rigidl connected with one of said bars for vertical y adjustin said gang-beam, and means for locking said andever on said frame for holding the gang in the desired position, substantially ,as set 1gTang beam fulcrumed toward its front end, a a'me extending upward from the rear end thereof, a horizontally-disposed lever fulcrumed between its ends to said frame, a ground -wheelto'the rear of the gang-beam, a

so as to cause said shovels to run atthe de caster-bracket in which said Wheei is swivin witness whereof I have hereunto affixed eled and which is ivotally connected with my signature in the presence of the Witnesses the rear end of said lever, and a connectingherein named. bar parallel with the rear end of said lever SAMUEL SEITNER.
